1999 PSD, 7.3L. Had it about a year. Has 130K Km. (80K miles) Rumour is it was parked for a couple of years before I bought it.

Has been smoking excessively for a couple of months, but only occasionally, on start up or when cold. When I leave home, I idle only a few seconds, then drive. I go about 2 km, mostly downhill to the highway. Couple of weeks ago, it was smoking at the hwy junction and hesitated when I accellerated onto the hwy. Smoke seems to be okay when driving, maybe just harder to see as it is spread over a larger area??

Yesterday, I hauled our new (to us) camper trailer about 400km from dealer to home. It made a knocking sound about 30 km from home, so I pulled over, idled 2 minutes, then shut down and had a look. No oil leaking evident. Oil level okay. I started up and saw moderate smoke. Got home okay.

Today I started it up and huge clouds of dark grey smoke and a slight ticking noise! I shut down,and noted oil level was below add mark. I added 2L. Then drove a couple of hundred yards to where I usually park. (lots of smoke, ticking noise) /Checked the oil again; too full! I guess it was more the slope the truck was parked on. So I drained out the 2L. and oil level seems okay. I don't think it is using oil, but not 100% sure.

What to do? I have an appointment with Ford dealer thurs. Should I drive it in (20Km.) or have it towed?

Any idea what is going on? Injector o-rings? Any ideas apprecieated. Thanks [img][/img] [img]sick.gif[/img]

 

Thread moved to the 7.3 forum... I think you'll get lots more answers here

And Welcome to FTE!

 

smoke sounds like unburned fuel
maybe injector

 

Yes, I think it is unburned fuel. What is going on?

 

i really think unburnt fuel is black! but i could be wrong! bad injector=engine shaking loss of power! but more ppl may chime in!

 

only 2 things can think of timing or injector with the ticking noise would think it would be an injector

 

o yes and welcome to fte!

 

you could be wrong if it is raw it is blueish white and stinks like hell

 

Unburnt fuel vapor is white smoke. Blue smoke is oil, and black smoke is semi-burnt excessive fuel in the condition of not enough air to burn the fuel. So what color is the smoke?

 

wrong again

 

Hmm, im gonna give my 2 cents here. When my truck was having gelled fuel, and i was loosing pressure, it would blow white smoke, and knock really loud. Might want to see if you have enough fuel pressure, im talking LOW fuel pressure<10psi and it would start to get bad. Sounded like an old tractor.

 

low fuel will cause white smoke and cause injector tick

 

Who is wrong again?

 

you are white smoke is insufficiant fuel blue is unburned fuel

 

Wouldnt fuel vapor be low fuel condition?
